Abstract
A method for isolating a yarn end of a broken warp thread from the warp in a weaving machine, the weaving machine being provided with a warp stop motion of the type wherein drop wires have been hung up on the warp threads for detecting that a warp thread has broken, includes the steps of first putting a yarn end of the broken warp thread in a correct position relative to the warp and subsequently removing the warp end from the warp. An apparatus for carrying out the method includes a clamp located on one side of the stop motion, a carrying element for tensioning the thread by hooking it and carrying it between the drop wires in a direction transverse to the warp direction, and a device located on a second side of the stop motion for removing the thread.
